This invention relates to bags made of openmesh material and paper, andwith regard to certain more specific features, to ventilated bags ofthis class.

This application is a division of our copending application, Serial No.53,708, filed October 9, 1948, entitled Bag of Open-Mesh Material andPaper, and issued August 28, 195'1, as Patent No. 2,565,754.

Among the several objects of the invention may be noted the provision ofan improved ventilated bag of the class described having a relativelylarge area of imperforate material suitable for printing labels on thebag; the provision of a bag of the class described which has excellentstrength and which provides for excellent visibility of products carriedtherein; the provision ofa bag of this class which may be formed in partof open-mesh fabric adapted for incorporation of a woven-in draw cord;and the provision of a bag such as described which may be manufacturedat low cost.

In general, a bag constructed in accordance with the invention has,among its principal features, a top section of open-mesh material in theform of a band forming the upper part of the bag body with the upperedge of this band dening the mouth of the bag, and a bottom section ofpaper in the form of a band forming the lower part of the bag bodyhaving its upper edge portion overlapping and secured to the lower edgeportion of the open-mesh section, the bottom lsection having its bottomclosed to form the bottom of the bag. Other features will be in partapparent and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations ofelements, features of construction, and arrangements of parts which willbe exemplified in the structures hereinafter described, and the scope ofwhich will be indicated in the following claims.

In the accompanying drawing, in which several of various possibleembodiments of the invention are illustrated,

Referring to Figs. 1-3 of the drawing, a bag of this invention is showngenerally to comprise a bottom section or band 5l of paper forming thelower end of the bag entirely, and a top section or band 53 of open-meshfabric material forming the upper end of the bag. As more particularlyshown in Fig. 2, the paper section 5| consists of two plies of paper,the outer ply being designated 55 and the inner ply 51. The paper may beof any suitable variety, such as kraft paper or, if desired, crepedpaper. The open-mesh fabric may be of any open-mesh Variety such as isordinarily used in bag manufacture, for example a leno or plain weave.

The open-mesh top section 53 of the bag is in the form of a girthwiseband forming the upper part of the bag body, with the upper edge 59 ofthe band defining the mouth of the bag. This open-mesh section is shownin Fig. 1 as having a draw cord 6I woven therein adjacent the mouthedge. The two-ply paper bottom section 5I is in the form of a bandforming the lower part of the bag body, and has its bottom closed toform the bag bottom. The lower edge portion of the open-mesh top sectionis sandwiched between the upper edge portions of the two paper plies andis secured therein, preferably by adhesive as indicated at A. The loweredge of the open-mesh section 53 is designated 62. It will be seen thatthe upper edge portion of the outer paper ply 55 overlaps the lower edgeportion of the top section on the outside, and the upper edge portion ofthe inner paper ply 51 overlaps the lower edge portion of the topsection on the inside. f

The bag shown in Figs. 1 to 3 may be made in production by combining acontinuous Web of open-mesh material with two continuous Webs of paper,one longitudinal marginal edge of the open-mesh web being sandwichedbetween the paper webs at one longitudinal edge portion thereof, andadhered therein to form a composite continuous Web. The open-mesh webmay have a draw cord woven therein extending longitudinally adjacent theother marginal edge of the open-mesh web. Then this composite web(including the draw cord) is severed along transverse lines spaced aparta distance corresponding to twice the width of the bags which are to beformed. Each blank thus obtained is of generally rectangular form andconsists of a generally rectangular top section of the open-meshmaterial which extends the full Width of the of the open-mesh sectionsandwiched betweenV` and secured to the paper plies at the upper widthiAs aboveA wise marginal edge portion thereof. stated, this securement ispreferably by adhesive. The blank is folded upona fold line, indicatedat 63 in Figs. 1 and 2 which extends heightwise across both the openmesh section and the twoufacture because they are formed in part ofrelatively inexpensive paper and thus require less of the relativelyexpensive open-mesh fabric than prior ventilated bags formed entirely ofopenmesh fabric, and because of being capable of manufacture by a simpleprocess.

In view of the above, it will be seen that the several objects of theinvention are achieved and vother advantageous results attained.

As manychanges could be made in the above constructions withoutdeparting from the scope ply paper section to bring the marginal edgesof the blank into substantial coincidence. Preferably, the edges of thefolded blank opposite the fold and at the paper end of the folded blankare turned or folded in and stitched together by stitching 65 thereby toseam these edges together thereby to yform side and bottom seams. While:a folded-in type of seam is illustrated, it will be understood thatother types of seam maybe employed. Such turning under of the edges asillustrated provides ior a better anchor between the stitching of theside seam and the open-mesh weave of the fabric. In addition, suchturning under aids 'the anchoring which is desired at 6l between theends of the draw cord Si, so that the opposite portion of the draw cordat B9 may now be pulled for closing the bag mouth. Such turning 'underalso 'forms a nished bag without the 'necessity of turning it insideout.

The above described operations result in the formation 'of theopen-mouthed draw cord bag illustrated in Fig. l having the open-meshsection 53 forming a Ventilating panel at the upper end of the bag', andhaving a paper bottom constituted by 'the two-ply paper section 5I. Thisbottom is closed by the bottom reach of the seam 65. The paper sectionprovides adequate area for imprinting labels. l

Fig. 4 illustrates a modification which is in all re's'pectslike themodification illustrated in Figs. 1 to 3 except that lthe inner paperply 5l is omitted. In this lform of bag, therefore, the paper bottomsection consists only of a single ply of paper 55, and this overlaps thelower edge portion of the open-mesh section on the outside, and 'issecured thereto, preferably vby adhesive A. In all other respects, themodification shown in Fig. 4 is exactly the same as that shown .in Fig.l.

The above-described bag constructions have several advantages over priorventilated bags. For example, they have an advantage over otheressentially paper bags with an open-mesh window insert. This is becausethe provision of a complete peripheral tubular section or band ofopenmesh material enhances strength. In addition, the use of such atubular section of open-mesh material at the top of the bag with theWovenin draw cord facilitates the provision of such a draw cord. Inaddition, the draw cord is not required to pucker any paper, but merelypuckers open-mesh fabric. Also the peripheral tubular band of paperprovides an economical label-forming area.

Thus, this invention provides a ventilated bag having a relatively largearea of imperforate material (the full area of the paper section 5|)suitable Afor printing labels and a perforate area `(the full area ofthe open-mesh section 53) `for visibility and for Ventilating the bagcontents.

The above-described bags are economical to manof the invention, it isintended that all matter contained in the above description or shown inlthe accompanying Vdrawing shall be interpreted as illustrative and notin a limiting sense.
